What do you coral polyps living together?

Coral polyps living together form a structure known as a coral reef. These small, individual organisms are interconnected and share a symbiotic relationship with zooxanthellae, a type of algae that provides them with energy through photosynthesis. By secreting calcium carbonate, coral polyps build the hard skeletons that create the reef structure, providing habitat and protection for a diverse range of marine life. This collaboration contributes to the biodiversity and health of ocean ecosystems.
